By the time the sun is in position to give max power, the batteries have been accepting a charge for at least 4 hours, and are no longer needing what they might have accepted IF full rate had been available hours earlier
As they charge internal resistance goes up, and it takes a higher voltage just to maintain that 8 amps, into the batteries
On a day with moving clouds, connect inverter turn tv and DVD, watch a movie, then go check the meter, you will see much higher Peak outputs recorded, and higher avg output reading
